I find this phrase extremely difficult to understand. 'Free wife' might be a concept where a wife is free in a certain context, but it's not clear what that context is. Regarding 'exposed i bodage sex stories', it's full of issues. The use of 'i' is wrong, and 'bodage' is likely a misspelling. If we assume it should be 'bondage', it could imply that a wife has exposed sexual bondage - related stories, but without proper context, this is all just speculation and an attempt to make sense of a very unclear statement.
The phrase is very confusing. 'Free wife' is not a common term. And 'exposed i bodage sex stories' has what seems like a misspelling ('bodage' instead of 'bondage' perhaps) and the 'i' in there makes no sense grammatically. It's hard to give a proper meaning without more information.
